Universal Joint Max and Min Angles

[rstock]

I have a universal joint connecting an actuator to a valve, and I need to determine if it's installation location does not cause the joint to exceed the maximum angle for that type of joint. Does anyone have a good reference that would give minimum and maximum angles for proper operation of a universal joint? Is there a standard for this or does it depend on the geometry of the joint? If it is geometry dependant, do you have a formula for calculating the maximum angle? Thanks.

You probably need to discuss it with the manufacturer. What is the duty cycle?

Automotive Hookes joints should be set at 4 degrees ideally.

Constant velocity joints have an articulation diagram based on angle AND plunge. The angle maxes out at 25 degrees, typically.

As long as you have articulation within the joints without physical interference, I wouldn't worry about it. Just make sure that your joints are parallel to each other to minimize angular accelerations.

Lots of information available on u-joints in automotive applications. Try googling words like drive shaft, drive line angles, drive line u-joints, etc.
